Formula and example
How it is calculated
ΔL = L₀ × α × ΔT; L₁ = L₀ + ΔL
Worked example
A length of 1 m with α = 12 µm/(m·K) increases by 0.6 mm for a temperature rise of 50 K.
Things to check
- A temperature difference of 1 K equals a difference of 1 °C.
- For accurate results, use the coefficient for the material and temperature range. Restrained components also develop stress.
